Still Loving the Smart! Can You Say HYPERMILER?

The car has only gotten better. Or maybe I should say that the driver has only gotten better.

I've learned some hypermiling techniques, and they've paid off. My mileage the first few fillups was about 41-42 mile per gallon. My last two tanks averaged nearly 49 mpg. In fact, last week I managed to squeeze nearly 419 miles out of my 8.7-gallon tank, with about .2 gallons to spare (an average of 50.4 mpg).

Here are my hypermiling tricks:
1. Drive slowly. No car can really perform better at 70 than at 60, due to aerodynamics and other reasons, so I drive at a steady 55-63 mph, pretty much. I think my average speed these days is about 57 mph on the highway. Hypermilers say that this can improve gas mileage like nothing else, and in my old car, I saw that this was definitely the case. I think that driving 70 costs 15-20% of your fuel efficiency compared with driving 60 mph. I think I'd drive 50 mph if I could, but that's almost dangerously slow, so I'll stick near 60. I won't mind when highways go back to a 55 mph speed limit.

2. Avoid using the brakes. I let the car slow itself down whenever possible, and I leave space before the car in front of me when I'm in any kind of traffic. The smart car's engine slows itself down as soon as your foot's off the gas pedal, and the deceleration is pretty strong because the car actually has an automated manual transmission -- it's like a stick-shift that does the shifting automatically. I've had trips from Manhattan to New Paltz where I used the brakes a total of three times.

3. Avoid hard accelerations, too. I like the advice that you should drive as tho there is an egg under the pedal. I read that the smart car has the slowest acceleration of any American car. Well, that makes my job easier! It just means I have to be careful when entering traffic to leave enough room behind me that I don't need to 'gun it.'

4. Draft when possible. I usually don't get to do this on account of point #1, but when a slow truck lumbers along, I'll sometimes keep up with it, watching my ScanGauge to make sure that the drafting is actually working (and it is, but it's still a bit hard to believe).

5. Drive other than in the center of the lane. This is some advice I read on a hypermiler site. I'm not sure if it's true or whether it makes a significant difference, but the idea is that the lane tends to wear out in the area where most cars drive, so you will do better by driving a bit left or right of that line.

6. Air in the tires! Make sure your tires are properly inflated. Some hypermilers even over-inflate theirs, but I'm not going to risk it in my tiny car -- the tires are small and hard enough as it is!
